Product Details

The ACL Bearings 1B663HD-01 is a high-performance connecting rod bearing from ACL's Race Series lineup, engineered for demanding motorsports applications and high-RPM engine builds. ACL Race Series bearings are recognized throughout the motorsports world for their superior durability and performance capabilities.

Advanced Performance Features:

  • High-strength overlay plate with reduced thickness for improved fatigue resistance
  • Hardened steel backing for enhanced bearing support and retention in the housing
  • Increased crush for improved bearing retention under extreme conditions
  • Eliminates flash plating on backing to maximize heat transfer and housing grip
  • Increased eccentricity compensates for bore distortion at high RPM
  • Tight, consistent wall tolerances help maintain precise bearing clearances
  • Enlarged ID chamfers accommodate large fillet radius performance crankshafts

ACL's unique combination of design, metallurgy, and engineering delivers the endurance and capability required in race engines that set records and win championships across multiple motorsports disciplines, from drift racing to NASCAR, IHRA, and NHRA competitions.

Great prices!

Great prices, filled and shipped immediately. Best deal around!

They have the best unbelievable prices and availability on all kinds of automotive products on the market and like I said the prices are great i will buy from here in the future

I pieced a roof rack setup from all over the internet, and Autoplicity consistently beat every other vendor on price and shipping, even most auctions on eBay!<br>I found the site confusing when searching for items directly (why was the "Roof Racks & Cargo Carriers" dropdown empty, when Google showed their ads for tons of these products?). Since they always came up at the top of a Google Shopping search for products, using their website's internal navigation wasn't ever necessary.<br>Customer service guy was a little snippy, but I could have just been interrupting his lunch.

Great!

Very fast shipping! Lowest prices as well! Will do business again
